LIQUID-FUEL BURNER.

Specification of Letters Patent.

Patented Dec. 11,1917.

Application filed April 11, 1917. Serial No. 161,248.

To all whom it may concern:

Be it known that I, WILLIAM WELS- HAUSEN, a citizen of the United States, residing at Allenhurst, in the county of Monmouth and State of New Jersey, have invented certain new and useful Improvements in Liquid-Fuel Burners, of which the following is a specification.

This invention relates to liquid fuel burners and while the burner embodying the present invention is designed primarily for use in conjunction with an automobile radiator heating system, the principles of the invention may find embodiment in burners designed for other uses.

It is one object of the invention to provide a liquid fuel burner Which may be lighted and left unattended with safety so as to su ply heat to the radiator for any desired l ngth of time to prevent freezing of the water therein and, incidentally, to provide highly eflicient means for automati-' cally feeding liquid fuel to the burner font as the fuel is consumed.

Another aim of the invention is to provide a burner of the class above mentioned which may be readily and quickly taken down so as to permit of convenient trimming of the wick, and cleaning of the burner parts and their repair if necessary. Incidentally, the invention aims to so construct the burner that the burner proper may be dismounted or taken down without in any way disturbing the means provided for antomatically supplying fuel to the burner so that the said means will not be likely to become disarranged and fail to properly perform its function when the burner proper is again mounted in position upon the radiator. Y In the accompanying drawings:

Figure l is a vertical transverse sectional view through the burner embodying the present invention, the view also illustrating a portion of the heating system for the radiator- Fig. 2 is a horizontal sectional view on the line 22 of Fig. 1 looking in the dlrection of the arrow;

Fig. 3 is a bottom plan new of the attaching member for the burner proper;

Fig. 4 is a side elevation of the said attaching member.

As before stated, the burner embodymg the present invention is designed prlmarily for use in a radiator heating system and such a system is disclosed in my co-pending application filed April 11, 1917, Serial No. 161,247, and in the drawings there is illustrated so much of the lower portion of such a radiator as is necessary to illustrate the application of the'burne'r, the numeral 1 indicating in general the base of the radiator and the numeral 2 indicating a flue through 'which the heated air currents from the burner ascend, the said flue extending upwardly within the radiator and having its lower end extending a short distance below the base 1 of the radiator and exteriorly threaded, as indicated by the numeral 3. The attaching member for the burner proper comprises a body 4 which is formed at one end with an opening 5, the wall of which is threaded to fit the threads 3 upon the projecting lower end of the flue 2, the upper face of the body 4 being plane to seat snugly against the underside of the radiator base 1 it being understood that the attaching body 4 is in this manner firmly supported beneath the radiator. For a purpose to be presently explained the underside of the body 4 is formed with an annular seat 6 surrounding the opening 5. In its said under side the body 4 beyond the opening 5 therein is recessed as at 22 to house the elements of the means provided for automatically controlling the supply of liouid fuel to the burner as will be presently described.

The burner proper includes a burner head 7 the periphery of which is designed to fit snugly within the seat 6 and this head has a number of perforations 8 through which air may enter to sustain the burner flame, the upper portion of the head being housed within-the lower end of the flue. The burner further includes a wick tube 19 surrounding Which is the usual wick 10 and this wick tube carries the usual flame spreader 11. The tube 9 is open at its lower end and extends axially within the burner font which is indicated by the numeral 12 and which is of suitable capacity and integrally connected by a web portion 13, with a float ill till

lid

passage.

ferred to as being formed in the, underside of the attaching body 4-. To prevent buckling, the bottom of the float chamber 14; is downwardly bulged, as at 17. The means provided for connecting the burner as a whole with the attaching member l is in the nature of a yoke including side members 18 and a lower connecting member '19, the yoke being disposed to straddle the attachmg body 4t and the float chamber 1% and the upper ends of the side members of the yoke being pivoted, as at 20, to the front and rear sides of the said body l. Thus the yoke may be swung to the position shown in Fig. l of the drawings, in which position its connecting portion 19 will extend beneath the bottom 17 of the float chamber or the yoke may be swu'n g outwardly to the position shown in Fig. 3 of the drawings. A binding screw 21 is threaded through the connecting member 19 of the yoke and may be adjusted, when the yoke is in the full line position shown in Fig. l of the drawings, to bear firmly its upper end against the downwardly bulged bottom 17 of the float chamber so as cause the upper end of the float chamber to seat the underside of the attaching body 41-, and the burner to seat firmly within the seat 6 in-the underside of the body. will now be understood that when is desired to remove the burner including the burner head, font l2, and float chamber" 1%, this may be readily accomplished byloesening the binding screw 21 and swinging the yoke to the left in Fig. l of the drawings, whereupon the parts mentioned may be bodily dropped from the attaching member l. (if course, by reversing this procedure the said parts may be quickly reassembled with the attaching member.

The recess heretofore referred to as formed in the underside of the body 4 is indicated by the numeral 22 and threaded into one end of the body is a nipple 23 for the connection of a fuel conduit (not shown) leading from any suitable source of supply upon the machine, the nipple communicating with a passage 2d formed in the body 4 and the said passage at its inner end opening into the recess 22 so that the liquid fuel suppliedthrough the said conduit will pass through the passage 24 and into the float chamber 14. Secured'upon the upper wall of the recess 22 beneath the inner end of the passage 24: is a guide 25 in which is vertically slidably mounted the stem 26 of a valve having a conical head 27 designed when moved upwardly to close the inner end of the passage 24: and cut-oil the supply of liquid fuel to the float chamber through this Pivotally mounted, asat 28., upon the said upper wall of the recess 22 is an arm 29 which extends beneath the valve 27 and upon which the lower end of the valve intense Removably disposed within the floatchamber, engages at its upper end with the free end of the arm 29 which end of the arm is preferably curved to form the annular head 32.

From the foregoing description of the invention it will be understood that as the 1 liquid fuel is consumed by the burner the level of the fuel within the float chamber it will lower as will also the float 31 and, consequently, the arm 29 will fall allowing the valve 27 to move downwardly to open position. Liquid fuel will then flow through the passage 24: into the float chamber unt1l the float 31 has again movedupwardly into engagement with the free end of the arm 29 the arm has moved the valve to closed position. Thus the supply of liquid fuel to the burner is entirely automatic and the burner may be lighted and allowed to stand unattended for any length of time without likelihood of too much or insufficient fuel being fed thereto. An overflow pipe 33 leads from the font 12 near the upper end thereof and is of larger diameter than the passage 2% so that should the float 8i fail v to operate, the liquid fuel will overflow from the said font, thereby indicating to the user of the burner that the float and parts actuated thereby require attention or adjustment.

Having thus described the invention, what is claimed as new is:

1. in a device of the class described, an attaching member having means for attach ment to a due, a burner detachably assembled with the said attaching member and llltl llll including a burner proper, a font, a float chamber communicating with the font, a float within the said chamber, the said attaching member having a liquid fuel conductor communicating with the float chamber when the burner is assembled with the said attaching member, and means carried by the attaching member for controlling the flow of liquid from" said passage and is designed to coact.
